Objective To observe the effect of Shenmai injection combined concurrent chemoradiotherapy on immune function in patients with locally advanced non-small cell lung cancer.Methods A total of 80 patients with locally advanced non-small cell lung cancer were randomly divided into treatment group and control group.In treatment group,40 patients received simultaneous three-dimensional conformal radiotherapy combined with TP(docetaxel+cisplatin)chemotherapy,while given Shenmai injection in the process of concurrent chemoradiotherapy.In control group,40 patients only received chemoradiotherapy.The changes of T cell subsets were observed between the two groups.Results It showed no significant differences in percentages of CD+3,CD+4,CD+16CD+56and CD+4/CD+8 ratio between two groups pre-treatment(all P＞0.05).There were no significant adverse reactions occurred after received Shenmai injection in treatment group.Conclusion It play an important role in improving immune function of patients with locally advanced non-small cell lung cancer who received Shenmai injection combined concurrent chemoradiotherapy.

Objective To investigate the infection status quo and genotype distribution of human papillomavirus(HPV) infection situation among females in west Guangxi area.Methods Cervical exfoliative cells samples from 3 315 women were collected to detect HPV genotyping with Cape flow-through hybridization.Then the results were statistically analyzed.Results The overall HPV infection rate was 21.30%(706/3 315),in the females of HPV positive infection,the high-risk type infection was predominant,accounting for 89.52%(632/706).The HPV infection type was dominated by single type infection,accounting for 72.66% the double infection accounted for 22.10%(156/706). The 21 HPV subtypes were detected.The high-risk HPV subtypes with high detection rate were HPV52(26.77%),HPV16(15.30%) and HPV58(15.01%).The low-risk HPV subtypes with high detection rate were HPV CP8304(11.90%) and HPV6(3.68%).The HPV subtypes were distributed differently at different ages.In 7 age groups of≤20,>20-30,>30-40,>40-50,>50-60,>60-70,>70 years old,the infection rates of high risk HPV were 21.62%(8/37), 19.26%(120/623),17.66%(220/1 246), 14.88%(153/1 028), 16.83%(51/303),15.52%(9/58) and 30.00%(6/20) respectively,showing no statistically significant differences among them(χ2=10.019,P=0.124).Conclusion Cervical HPV infection are mainly high-risk HPV subtypes and single type infection in females of western Guangxi area.The HPV subtypes with high infection rate are 52,16,58 and CP8304.

Objective To investigate the correlation between the level of presenilin-associated rhomboidlike protein (PARL) and the sperm motility,survival rate and deformity rate of sperm in workers exposed to aluminum.Methods A total of 162 male workers exposed to aluminum in a large aluminum enterprise in Guangxi were selected as the exposure group,and the 162 staff members of the service company were selected as the control group by matching the age and length of service.The concentration of aluminum in the working environment and the aluminum content in the blood and urine were determined by graphite furnace atomic absorption spectrometry and high performance liquid chromatography.Enzyme linked immunosorbent assay was used to measure the level of PARL protein in sperm and sperm function was evaluated.Results The average concentrations of aluminum in the batching,electrolysis and casting of aluminum exposure group were (6.72± 1.45),(7.23± 1.50) and (7.35± 1.72)mg/m3,which were significantly higher than those of the control group (F=8.314,P＜0.001).The content of aluminum in blood and urine of exposed group were significantly higher than those of control group (P＜0.05),while the levels of PARL of exposed group were significantly lower than those of control group (P＜0.05).Moreover,the sperm survival rate and sperm motility of exposed group were significantly lower than those of the control group,and the sperm deformity rates of exposed group were significantly higher than those of the control group(P＜0.05).Pearson correlation analysis showed that there was a positive correlation of sperm motility,sperm survival rate and protein level of PARL (rsprm motility=0.713,P=0.012;rsperm survival rate =0.628,P=0.008);while the sperm deformity rate and protein level of PARL showed a significant negative correlation (rsperm deformity rate =0.953,P =0.002).Conclusion The sperm function was significantly impaired in aluminum exposed workers,and the changes of sperm motility,survival rate and malformation rate were closely related to the protein level of PARL.

OBJECTIVETo explore the central mechanism of postoperative fatigue syndrome by detecting the expression of NMDA receptor and tryptophan metabolism.

METHODSAfter being numbered according to the weight, ninety-six male SD rats were randomly divided into control group (bowel loop was flipped after laparotomy and received intraperitoneal injection of saline at a dose of 1 ml/kg), POFS model(70% of the length of small intestine was resected and received intraperitoneal injection of saline at a dose of 1 ml/kg), and NMDA antagonist groups(70% of the length of small intestine was resected and received intraperitoneal injection of MK801 at a dose of 1 ml/kg). Each group was divided into subgroups by postoperative 1, 3, 5 and 7 d, with 8 rats in each subgroup. The hippocampus was removed at each time point after open field test (OFT) to detect the mRNA expression levels of NMDA receptor 1 and kynurenine aminotransferase III((KATIII() by real-time PCR. Protein level of NMDA receptor 1 was detected by Western blot. High performance liquid chromatography (HPLC) was used to measure the concentrations of tryptophan (TRP), kynurenine (KYN) and kynurenic acid(KYNA). Ultra-structural changes of hippocampal neurons were observed by transmission electron microscopy(TEM).

RESULTSAs compared to control group, exercise score decreased(P<0.05), rest time and central panel residence time prolonged, periphery/central panel ratio increased (all P<0.05), mRNA and protein expressions of NMDA receptor 1 increased (P<0.05), mRNA expression of KAT III( decreased (P<0.05), KYN/TRP ratio and KYN/KYNA ratio decreased (all P<0.05) in POFS group on postoperative day 1 and 3. As compared to POFS group, central panel residence time and periphery/central panel ratio decreased on postoperative day 1, and mRNA and protein expressions of NMDA receptor 1 decreased on postoperative day 1 and 3 (all P<0.05) in antagonist group. TEM revealed that degenerated neuron was found in the hippocampus of POFS rats, while such damage was improved in antagonist group.

CONCLUSIONThe increased expression level of NMDA receptor may play an important role in POFS. NMDA receptor antagonist MK801 may improve the POFS.

Objective:To evaluate the efficacy and safety of sodium hyaluronate gel in preventing adhesion after prophylactic enterostomy.Methods:One hundred and twenty four patients from 6 hospitals were enrolled in this prospective multi-center randomized controlled trial. Patients were randomized into the study group ( n=59) or the control group ( n=65).All patients underwent prophylactic enterostomy. Patients of study group received odium hyaluronate gel for adhesion-prevention,while those in control group did not receive any adhesion-prevention treatment. The incidence of moderate to severe adhesion around the incision in the stoma area were evalutated during stoma reduction surgery. Results:The incidence of moderate to severe adhesion around the incision in the stoma area was 6.3% in the study group, the difference was statistically significant ( P<0.05) compared to that of the control group (32.6%). Conclusion:Sodium hyaluronate gel can safely and effectively reduce the incidence of moderate and severe adhesions after abdominal surgery.
